FBI releases its records on Whitney Houston

FILE - This April 25, 2010 file photo shows U.S singer Whitney Houston performing at the o2 in London as part of her European tour. The FBI has released its files on a trio of investigations the agency conducted on behalf of Whitney Houston. The records released Monday show the agency conducted one investigation into an alleged extortion attempt in 1992, but agents and prosecutors determined no crime occurred. Agents also found no evidence of criminal threats to the singer in fan mail that was sent to the FBI for investigation in 1988 and 1999. The 128-page file covers the height of the Grammy-winning singer's popularity but does not contain any new personal details. (AP Photo/Joel Ryan, file)
